Opacity readings
WebHydrocarbons (HC) HC is an organic compound composed of Hydrogen (H) and Carbon (C) atoms. The HC in gasoline engine exhaust is unburned gasoline vapor (a mix of Hydrocarbon compounds) that is measured in parts per million (ppm) equivalent Hexane (C6H14). HC levels in engine exhaust vary with the air-fuel ratio. WebOpacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light. In radiative transfer, it describes the absorption and …
